Abstract: Method and apparatus for electrophotographically transferring a developed color image on the surface of a photoconductive drum (10) directly to an adjacent print media (30). The print media (30) is operative to pass between the one abutting surface location on the photoconductive drum (10) and an adjacent surface location on a transfer roller (28) which is connected to receive a DC bias voltage (42). Once a composite color image has been developed on the surface of the photoconductive drum (10), this surface is illuminated with light (76) within a chosen wavelength range and intensity to thereby cause hole-electron pairs within a layer of the photoconductive drum (10) to recombine and thereby reduce the net voltage across the photoconductive surface layer or layers to a level on the order of about thirty (30) volts. In this manner, the DC bias voltage (42) applied to the direct transfer roller (28) can be made larger than otherwise possible,thereby increasing the maximum achievable electrostatic field strength between the surface of the transfer roller (28) and the photoconductive drum (10). This feature of increasing the electrostatic field strength across the print medium (30) provides image transfer fidelity and print quality during the electrophotographic printing process.

Abstract: A small autonomous radio timepiece (11) with an analog display, in particular a radio travel clock or radio wristwatch, is to be fitted with handling and signalling means with the aid of which it is possible to realise functional operation which is as unambiguous and comprehensible as possible and versatile in the process, as well as the transfer of information without a large overall volume. For this purpose, a multiple switching device (19) having momentary contact switches (Ti) is realised, by which the contents of a time zone addition register (44) can be interrogated, or varied by time zone units with the aid of a momentary contact switch (T2) which can be operated in a time-coded manner, or can be transferred to the analog display (13). A separate momentary contact switch (T3) is used to return the time display to that time zone for which the time transmitter is being operated to which the receiver (31) is currently tuned, without in the process changing the contents of the time zone addition register (44), with the result that the operational sequence T3-T2 produces an analog dual time display. A momentary contact switch (T1) which can equally be operated in a time-coded manner can be used to interrogate whether the receiver turn on (1) in the recent past lead to the decoding of a usable item (37) of time information, and it is possible to initiate a transmitter call in conjunction with internal updating of the autonomous time measurement, with acceptance of the internally updated time if it has not been possible within a prescribed receiver switch-on time interval to demodulate and decode a usable item (37) of time information. An operation of the keys which initiates a restart accompanied by register reset also causes the timepiece to start outside the receiving area of a time-information transmitter and to operate self-sufficiently with internal time holding after a time register reset. <IMAGE>

Abstract: Image data representing multi-dimensional objects is processed. The position of objects in space is calculated and lighting characteristices are calculated, in response to positional and surface data. 
     Conventional floating point arithmetic is performed when calculating the position of polygons, particularly during transformations and projections etc. However, advantage is taken of the fact that a limitation exists in the number of bits available for representing the final 2-dimensional image. 
     Consequently, lighting characteristics are calculated in lower accuracy fixed point airrithmetic, also known as integer arithmetic.

Abstract: The techniques for determining the orientation of lines in images disclosed herein take as their starting point an apparently universal typesetting convention: that symbols are generally closer to other symbols in the line to which they belong than they are to symbols in other lines. The techniques make a graph by connecting symbols in an image of a block of text with edges (lines) and then determine the predominant orientation of the shortest edges. Because the symbols in a line are closer to each other than to symbols in other lines, the predominant orientation of the shortest edges will be the same as the orientation of the lines. An advantageous mode of obtaining the shortest edges is to construct a Euclidean minimum spanning tree from the graph. A Euclidean minimum spanning tree of a graph contains all the nodes (symbols) of the original graph but connects the nodes with the shortest possible set of edges. The edges which predominate in the Euclidean minimum spanning tree are the shortest edges. Which edges predominate is determined by means of a histogram.

Abstract: A wire position correcting device is used with a terminal mounting apparatus A for mounting a terminal fitting on a wire E fed between a crimper 32 and an anvil 20 from a side. A rotatable member 60 is provided which rotates as the crimper 32 moves upward and downward. The rotatable member 60 rotates when the wire E is fed and presses a specified position of the wire E to correct the position of the wire E so that the terminal fitting can be properly mounted at an end of the wire E. 
     Accordingly, the end of the wire E can be accurately placed right on the fed terminal fitting during a terminal mounting operation. Even if the wire E is curved or deformed while being fed, the terminal mounting operation can be constantly properly performed. The mount position of a wire holding member 50 needs not be finely adjusted.

Abstract: An alternator (3) includes MOSFETs (51-56) used as rectifiers which are sealed by a sealing member (72, 74) (for example, a molded epoxy resin) together with heat radiating fins (42, 43) and an external input/output terminal plate (44). The sealing member (72, 74) can evenly dissipate stress even if the radiating fins (42, 43), terminal plate (44), and the like vibrate with different phases. Since the rectifying elements (51-56) are reliably secured even when subjected to great vibrations, damage to the MOSFETs (51-56) can be suppressed. The MOSFETs (51-56) are never exposed to atmospheric air since the MOSFETs (51-56) are sealed by the sealing member (72, 74). Therefore, the alternator (3) can improve the MOSFETs' (51-56) resistance against adverse operational conditions.
